68 Barracuda Mini Tub rear end ?

Have a fastback 68 bcuda and plans are to minitubb it. I am wondering about the rearend. I am replacing the orginal one with a Dana 60 and wondered how much shorter would be good to go for a 305 or 325 tire and be able to get wheels without breaking the bank? Wheel wells will be stretched to the frame. The dana will be a drum rearend. Seeing how I am cutting down a truck dana 60 I might as well do it so I can afford a set of rims for the car.

If anyone has already done this I would love to pick your brain and see some photos of your car.
